What The Keto Diet Actually Does To Your Body | The Human Body


The ketogenic diet, or keto, has become a popular way to lose weight. The high-fat, low-carb diet is a drastic change from the diet that the USDA recommends for Americans. It’s also a huge change for your body’s metabolism.

And while keto is proven to help you shed the pounds, the diet can come with some side effects, like the notorious keto flu.The high-fat, low-carb ketogenic diet, or keto for short, has become a popular way to lose weight. And while keto is proven to help you shed the pounds, it’s a huge change for your body’s metabolism and can come with some serious side effects.

Following is a transcript of the video:

Step aside Atkins. There’s a new fad diet in town.

The ketogenic diet, or keto for short. Celebrities like Halle Berry, Kourtney Kardashian, and Vanessa Hudgens all swear by it.

And if losing weight is your goal, keto works! It’s proven to help you shed pounds fast. But there’s more to this diet than meets the eye.Keto basically replaces carbs with fat. A typical keto diet looks like this: 70% fat, 25% protein, 5% carbohydrates. It’s a drastic change from the diet that the USDA recommends for Americans: Less than 30% fat, 20-35% protein, at least 50% carbs, and it’s a significant change for your body’s metabolism too. Usually, when you eat carbs, like a starchy potato, enzymes in your mouth, stomach, and small intestine break them into a form of sugar energy, called glucose, which your brain and body use for fuel.

So, when you skip out on carbs, the first couple of days you might experience some strong sugar cravings. Because your body is switching gears, from burning carbs to the only energy it has left: fat.

Once you’re burning fat regularly, you’ll start to see the pounds melt away. Depending on your weight, you might lose up to 3.5 pounds within the first week. As you burn more fat, levels of insulin — the fat-storing hormone — will drop significantly. This triggers your kidneys to release large amounts of sodium into the blood.

Which can actually lead to a common side effect known as the “keto flu.” Many keto dieters report symptoms like: Nausea, Headaches, Dizziness, Muscle cramps, and low energy levels.

But most of these symptoms will only occur within the first couple weeks of starting the diet.

After the first month, the scales will look better. But some of that lost weight isn’t actually fat. It’s water.

Because some of the carbs you’ve metabolized include glycogen, which retains water and therefore helps keep you hydrated. As a result, you’ll likely pee more, which will lower your sodium levels even more, leading to: Dehydration, Constipation or diarrhea, and bad breath.

Once you’re a couple months in you might hit the notorious keto plateau. It’s a common term in the keto community and refers to when people find it harder to continue losing weight. One study, for example, found that overweight people lost an average of 15 pounds in the first month. Another 11 pounds over the next two months. But after that, they saw no change in body weight — despite sticking to the keto diet.

At this point, many people quit keto. That’s why researchers often find it hard to study the long-term effects of the diet. But, as it turns out, there is one group that typically sticks to keto.

It’s unclear why, but keto has been proven to reduce the symptoms of epilepsy. And studies show that epileptic children who stay on very restricted keto diets for several years can suffer from: Kidney stones, High cholesterol, and bone fractures.

But a typical keto diet won’t be nearly as strict and if you do want to try keto, you should talk to a doctor first. In the meantime, go ahead and enjoy that bread and remember, the best diet is a balanced one of fat, protein, and — yes, even — carbs.

What The Keto Diet Actually Does To Your Body | The Human Body





  1. Ive seen many vids on keto and this is the first where anyone has put it down… so far as a healthy diet.. it looks good to me and the comments of most that have used it are great.. and I have friends who have had great success… so Im going to try it… all Ive seen back up the results I was after from having a stroke too and gaining weight from complications from it.. this diet has all the brain food I eat anyway. just puts it into a better format to help recalibrate the rest of my body to stop the onset of diabetes and high blood pressure which Im now suffering from… Im giving Keto a go… I want a tune up and change … heres hoping

  2. this video is so simplistic. I just started the infamous keto and I needed this switch from carbs, which had been the basis of my diet for decades. I'm also intermittent fasting and that's an eye-opener — what the body can do, how habits can change, how a certain je ne sais quoi returns. no one thing is the answer. paying attention to your body is key. and not following "medical" advice.

  3. I am more low carb. I have one to two slices of low carb bread a day, make a Keto oatmeal (Joe Duff) in the microwave. I occasionally have half a cup of cooked pasta, green bananas and a slice of orange. But gone are potatoes, rice, starchy vegetables and processed foods with sugar. I've lost 35 pounds in four months and looking to lose at least 20 more.

  4. Eating a lot of vegetables is a big part of keto too, & you don't just eat fat you get it from nuts, dairy & meats. Eating 7 cups vegetables, 1 gram of protein per lean body weight & the rest of caloric need from nuts & dairy Is good healthy keto. This guy needs to research the subject he is trying to make videos on he is talking about Atkins not keto

  5. Another hit piece from the friends of big pharma! Remember folks, big Pharma doesn't make trillions off of healthy people, they make trillions off of sick people.

    FUN FACT! Pharmacy, pharmaceutical, etc is derived from the ancient Hebrew pharmakeia which means sorcery.

  6. No any diet which sustains calorie deficit can helpt u lose muscle and fat that is weight.keto is no special for loosing weight , yes but it may help u with acne problems and other,
    Also when people hit keto plateau after losing weight for few months that happens because u are eating the same amount of calories which u were eating when u were obese, since now u have lost some weight, u need to recalculate your maintainence calories and then do a keto diet within keeping the new number in mind. When u lose weight again, recalculate the maintainence calorie and then again eat keto diet in defecit, u will soon reach a number below which u cant really go, thats where cardio comes into play, eat more burn more
